firmly, because the original test in the grave will be one based on creed. Salah, fasting, hajj, zakat, etc. will also be accounted for, but on the Day of Judgement. In the grave, there will be three questions:

1.  Who is your Lord?

2.  What is your religion?

3. What did you use to say about this person (i.e. the final Prophetصَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم)?

These three questions are all creedal in nature. Therefore, always ensure your beliefs are unshakeable. Always ensure that your beliefs regarding Allah Almighty, the final Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, the divinely revealed books, the prophets and messengers رَضِیَ اللهُ عَنْهُم, the angels, the Prophetic Companions رَضِیَ اللهُ عَنْهُم and the Prophetic Household رَضِیَ اللهُ عَنْهُم, are in line with the beliefs held by the Prophetic Companions رَضِیَ اللهُ عَنْهُم, noble saints رَحِمَهُمُ الـلّٰـهُ and Sunni scholars over the centuries. If we adopt the correct Islamic beliefs and remain steadfast upon them, اِنْ شَــآءَالـلّٰـه we will be saved from the punishment of the grave.

The grave is expanded as far as one can see

It is narrated from Sayyidunā ꜤAbdullāh b. ꜤAbbās رَضِیَ اللهُ عَنْهُمَا that the Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said:

Indeed, when the people return after placing the deceased into his grave, he hears their footsteps. Then he is sat up and asked, “Who is your Lord?”

So, he replies, “Allah Almighty.”

Then, it is said to him, “What is your religion?”

He responds, “Islam.”

Then, it is said to him, “Who is your Prophet?”
